Dangerous job of electricians
In addition to the workplace hazards generally faced by industrial workers, electricians are also particularly exposed to injury by electricity. An electrician may experience electric shock due to direct contact with energized circuit conductors or due to stray voltage caused by faults in a system. An electric arc exposes eyes and skin to hazardous amounts of heat and light. Faulty switchgear may cause an arc flash incident with a resultant blast. Electricians are trained to work safely and take many measures to minimize the danger of injury. Lockout and tagout procedures are used to make sure that circuits are proven to be de-energized before work is done. Limits of approach to energized equipment protect against arc flash exposure; specially designed flash-resistant clothing provides additional protection; grounding (earthing) clamps and chains are used on line conductors to provide a visible assurance that a conductor is de-energized. Personal protective equipment provides electrical insulation as well as protection from mechanical impact; gloves have insulating rubber liners, and work boots and hard hats are specially rated to provide protection from shock. If a system cannot be de-energized, insulated tools are used; even high-voltage transmission lines can be repaired while energized, when necessary.
Electrical workers, which includes electricians, accounted for 34% of total electrocutions of construction trades workers in the United States between 1992?2003.
NEC - definition by Wikipedia
The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. It is part of the National Fire Codes series published by the National Fire Protection Association (NFPA), a private trade association. Despite the use of the term "national", it is not a federal law. It is typically adopted by states and municipalities in an effort to standardize their enforcement of safe electrical practices. In some cases, the NEC is amended, altered and may even be rejected in lieu of regional regulations as voted on by local governing bodies.
The "authority having jurisdiction" inspects for compliance with these minimum standards.
Specialty car mechanic
Very often we meet with automotive workshops that offer electrical services. They belong to the same frequently used services, such as services varnishing or mechanics. As you know, a major failure associated with electricity in the car can lead to significant deficiencies and prevent the smooth functioning of the car. Therefore, many people use the services of electricians employed in garages. You could say that as a specialty electrician person working in the garage is very much needed, because the newer the car, the more it solutions for electrical and electronics, and you need a particular specialist, to effectively remove the fault.
